A New Cd(II) Coordination Polymer with a Rare tfz-d Topology Constructed by Asymmetrically Tricarboxylate and Imidazole-Containing Ligand: Synthesis, Crystal structure and Luminescent Property

Abstract

A new coordination polymer [Cd(Hbtc)(bib)0.5]n (1) (H3btc = biphenyl-3,4′,5-tricarboxylate and bib = 1,4-bis(imidazol-1-yl)benzene) has been obtained under hydrothermal conditions. The structure of complex 1 has been determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis and IR spectrum. The complex 1 shows a (3,8)-connected twofold interpenetrated three-dimensional (3D) tfz-d topology with the point symbol (43)2 (46·618·84). The photoluminescence behavior of complex 1 was also discussed in paper.
